GASOLINE CLARIFIER.

Application filed October 21, 1926. Serial No. 143,201.

This invention relates to gasoline clarifiers and more particularly to adevice of this character adapted for use in cleansing the gasolineemployed in cleaning establishments.

An important object of the invention is to provide a device of thischaracter in which the cleaning of the gasoline is expedited and at thesame time a product provided which is free from impurities of any sort.

A further object of the invention is to providea device of thischaracter which prevents introduction of air into the cleaning tank withthe gasoline. In many devices of this character, the construction issuch that air enters with the gasoline, with the result that thesolution is disturbed and rapid clarification of the gasoline prevented.

.A further object of the invention is to provide a device of thischaracter wherein the'pressure applied to the gasoline injected into thecasing is prevented from fluctuating rapidly, so that the contents ofthe container will move uniformly and the cleansin ope-ration canaccordingly be very accurate y controlled.

These and other objects we attain by the construction shown in theaccompanying drawings, wherein for the purpose of illustration is shown,a preferred embodiment of our invention and wherein Figure 1 is-avertical sectional view of a gasoline cleaner constructed in accordancewith our invention; I

Figure 2 is a section on the line 22 of Figure 1; v

Figure 3 is a section on the line 3-3 of Figure 1.

Referring nowmore particularly to the drawings, the numeral 10 indicatesa casing, at present shown as rectangular in form and has its bottom inthe. form of a funnel 11, the lower end of which is provided with avalve control drain opening 12. Immediately above the upper end of thefunnel, the casing 10 is provided with an outlet 13, whlle at its upper.end a further outlet 14 is provided. -The top of the casing is prov dedwith a removable cap 15. Extending into 9 the casing adjacent the lowerend thereof is a conduit 16, the inner end of which s provided with anextension 17 co-axial with the casing and havin at its lower end ad1stributor head 18 rom; which radiate a plu-' rality of dischargenozzles 19. The outer end of the conduit 163 communicates with avertical stack 19 of greater diameter than the conduit. The upperextremity of this stack is vented at 20 and is provided with an inlet 21arranged below the vent and adapted for connection with the usualgasoline pump of the cleaning apparatus. Adjacent the casing 10, theconduit 16 has associated therewith -a funnel 22, the outlet 23 of whichis valvecontrolled. This funnel provides a means for introducing to thefunnelshaped bottom 11 of the casing 10 a commercial alkalized solution,such as is ordi narily employed in cleansing gasoline.

Arranged within the casing 10 is a rack comprising vertical supports 24,the lower ends of which rest upon the inner faces of the walls of theconical bottoms 11 adjacent the tops thereof. These racks support aplurality of horizontally extending .bafile plates 25, each of a lengthless thanthe width of the casing and each having one end extending closeto the wall of the easing and the opposite end spaced therefrom. Thespaced ends of the baflle plates 25 are al- 89 ternated, so that acircuitous path is pro- 'vided for liquid arising through the plates.

The edges of the baffle plates 25 which are spaced from the casing areeach provided with downwardly bent lips 26 arranged at an acute angle tothe plate and adapted to catch any floating material carried b theliquid passing between the plates. bove the channel 27 provided betweenthe upper: most plate 25 and the wall of the casing, a further baflieplate 28 is disposed to insure proper distribution of liquids andprevent these liquids from arising in a vertically moving current whichwould cause all impurities carried thereby to engage against lter 29arranged above the rack. The filter 29 is formed by providing twoscreens 30 and 31 of suitable mesh and of a size to fit within the wallsof the casing. The screen 30 rests direct] upon the upper ends of the100 standards 24 o the rack and upon the screen is placed a suitablefiltering medium, such as cotton seed hull,,cotton batting, waste orsimilar material which will remove from the liquid any floatingsubstances, such as might 105 pass-the lips 26. The screen 31 is thenplaced on top of this material and has its upper surface immediatelybelow the level of the outlet 14. The stack 19' hereinbefore mentionedshould have its upper end well spaced above the upper end of thecontainer 10;

In operation, through the ity leaves Within the alkali solution, themajor portion of the dirt carried thereby. As the gasoline rises throughthe path provided by, the baflle plates 25, floating substances will becollected by the lips 26' and removed therefrom. In its passage throughthe filter 29, any

other substances carried thereb will be removed. Pure gasoline is withrawn from the outlet 14: and returned to the cleaner. Dirty gasoline andmuck may be removed through 'kali solution and any sediment containedtherein may be drawn through the outlet 12. It is pointed its filteringmaterial readily replaced at any time and that in cleanin the filter, itis mere- 1y necessary to remove t e cap 15, withdraw the filter and rackfor cleansing and then the outlet 13 and the. al-

out that the filter 29 may have withdraw the dirty gasoline and alkalisolution.

Since the construction hereinbefore setfort-h is capable of a certainrange of change and modification without materially departing fromthe-spirit of the invention, we do not limit ourselves to such specificstructure except as hereinafter claimed.

We claim v A gasoline clarifier comprising a casing having afunnel-shaped bottom wall, a filter disposed across the upper part ofthe casing, a conduit pipe passing through the side of the casing, andhaving an end extension disposed co-axial with relation to thefunnelshaped wall of the casing, a distributing head located in thefunnel-shaped wall of the casing and attached to the extension of saidconduit, radially disposed nozzles carried by the head, a verticallydisposed stack for supplying gasoline to theconduit, said stack avingits upper portion disposed above the level of the filter, and means forsupplying an alkali to the conduit between the stack and the casing.

In testimony whereof we. hereunto aifix our signatures.
